Hi @lumao,

seems like you didn’t build the dcsTest app with the same sources as on your device.

Which version do you have on your device? 16.10.3 ?

If so you need to checkout Legato 16.10.3 sources:

$ mkdir workspace
$ cd workspace
$ repo init -u git://github.com/legatoproject/manifest -m legato/releases/16.10.3.xml
$ repo sync

hi CoRfr,
here are the info of versions:

root@swi-mdm9x15:~# legato version
16.04.0_63633d9200de787b7c2a6dca03d2cff3_modified
and the Legato Packages (by version):
16.10.1.wp85-wp75-native-i686-201702141553

And I built my app follow a wizard with Legato Project from local existing code.

Hi @lumao,

In that case you will need to update your WP85 to 16.10.1, which is provided by release 13.1: https://source.sierrawireless.com/resources/legato/wpfirmwarerelease13_1/

hi CoRfr,

you are correct! All of the issue are solved when I update my WP85 to 16.10.1 :blush:

the explicit reasons Legato Package version did not compatible with my WP version.

Thank you.
